DNA synthesis takes place in _ phase of the cell cycle.
Correct answer: D. S
- A. G0
- B. G1
- C. G2
- D. S
Explanation
G0 phase: This phase is a resting phase of the cell cycle. Cells in G0 are not dividing, but they are still metabolically active. G1 phase: This is the first growth phase of the cell cycle. During this phase, the cell grows in size and synthesizes proteins and RNA. G2 phase: This is the second growth phase of the cell cycle. During this phase, the cell prepares to divide by synthesizing proteins and RNA. S phase: This is the synthesis phase of the cell cycle. During this phase, the cell replicates its DNA.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
